$BTC Bitcoin (BTC) is the world’s first and largest cryptocurrency by market capitalization. Created in 2009 by an anonymous entity known as Satoshi Nakamoto, Bitcoin operates on a decentralized, peer-to-peer network using blockchain technology. It serves as both a store of value and a medium of exchange, free from central bank control.

As of March 21, 2025, BTC is trading around $83,798, with high volatility. Its adoption continues to grow, with institutional investments, nation-state adoption, and Bitcoin ETFs gaining traction. The upcoming Bitcoin halving in April 2024 is expected to impact supply and price dynamics. Despite market fluctuations, Bitcoin remains the dominant asset in the crypto space, often referred to as “digital gold.”
